Myths vs facts: IgG Unverträglichkeitstest and Haut

IgG food intolerance tests are frequently marketed for skin issues like acne, eczema, or rosacea. However, scientific evidence does not support their use. Elevated IgG levels typically reflect normal immune memory to foods, not intolerance or allergy. Controlled studies have failed to show a consistent link between IgG results and skin symptoms. Major allergy and dermatology societies advise against these tests due to high false-positive rates and risk of unnecessary dietary restrictions. For skin conditions, evidence-based approaches include IgE testing, elimination diets under medical supervision, and dermatological treatment. Consumer tests like MyBody-X can provide general insights but should not replace professional diagnosis. Always consult a dermatologist for persistent skin problems.
